Fibrosarkome

Fibrosarcomas are a type of malignant tumor that arises from fibroblasts, the cells that produce fibrous connective tissue. This tissue is found throughout the body, meaning fibrosarcomas can develop in various locations, though they are most commonly seen in the soft tissues of the limbs and trunk.

These tumors are characterized by their unspecialized, spindle-shaped cells that produce excessive amounts of collagen. The appearance of fibrosarcomas under a microscope can vary, but they are generally considered to be aggressive and have the potential to invade surrounding tissues and metastasize to distant sites, such as the lungs.

Diagnosis typically involves a biopsy, where a sample of the tumor is examined by a pathologist. Imaging techniques like MRI or CT scans can help determine the size and extent of the tumor. Treatment options depend on the size, location, and stage of the fibrosarcoma, and often include surgical removal of the tumor. Depending on the aggressiveness and spread, radiation therapy or chemotherapy may also be used. The prognosis for fibrosarcomas can vary widely, with factors like tumor grade and presence of metastasis playing significant roles. Regular follow-up care is crucial after treatment to monitor for recurrence.
